Whenever I enable multiple monitors, one of the monitor screens (random screen) would freeze, while the extended one would be working. This only happens in the RC4 and RC5 kernel. However there are no issues on linux 45.
I see no errors in Xorg logs. I understand that RC kernels is for testing but I am really keen on this kernel as it contains an important patch for intel haswell CPUs scaling.
